Abacus International Math Challenge is a British website for grades 3/4, 5/6, and 7/8 students. Students complete different math tasks and may choose to submit their solutions to the author of the task for comments.

Grade 7-9 Numeracy Tasks were developed to help our students to become mathematical thinkers. Simon Fraser University created these tasks to help teachers create a learning environment to promote "mathematical thinking". These tasks require students to make decisions about assumptions they have. The role of the teacher is to help students decode the task, but then leave the students alone to work in groups to solve the task.
